The very next day, however, three more students were arrested in a subsequent fight; all 18 are currently suspended and could face expulsion.

While parents are worried, the district insists the school is safe and did not have any fights since Tuesday's incident. Hillside Police note there were no injuries or gang-related activity, though Police Chief Joseph Lukaszek told Fox social media has fueled the scare.

“There’s so much misinformation put out on Facebook, Twitter accounts, that we have to react," said Lukaszek. "And when we find threats, we review them and look into it, and try and see if the information is good or not."
